Tumor patients often have the following situations in the process of diagnosis and treatment 1. They think that the surgery is very successful and there is no need for post-operative review, or they do not go to oncology department to consult whether they need radiotherapy and chemotherapy until the tumor recurs and symptoms appear! 2. In the process of radiotherapy and chemotherapy, once the treatment fails to achieve the expected goal, they quickly ask the doctor to change the treatment plan, or frequently change the hospital and doctor, so that the treatment that should be systematic is messy due to different treatment plans, and finally, people cannot start the treatment. 3.During the treatment process, they do not pay attention to save the examination or treatment information, such as each chemotherapy plan, medication, time, etc. These information are very important for the future review of tumor, or the retreatment after recurrence, and must not be disposed arbitrarily. If patients with recurrence go to the hospital again, they must carry complete information of previous treatment, if they cannot find it, they should try to describe it clearly, because many previous treatments have influence on subsequent treatments, for example, patients with previous radiotherapy should be very careful when they go for radiotherapy again.
